Some of the elements of your semi-submersible rigs and platforms that CSD Sealing Systems can protect with our world leading solutions:

Semi-submersible rigs and platforms
Sealing systems designed for the world’s most demanding offshore environments. Semi-submersible rigs operate in some of the harshest conditions in the energy industry – exposed to constant movement, saltwater, pressure and extreme weather. CSD’s sealing systems are trusted globally to protect these critical offshore assets, providing long-term defence against fire, water, gas, smoke and electromagnetic pulse (EMP).
Designed for semi-submersible rig and platform demands
Our solutions are engineered to maintain compartment integrity and prevent the spread of hazards between zones, even under dynamic load or vibration. Whether for new-build platforms or life-extension projects, CSD systems deliver certified, maintenance-free performance.
Applications on semi-submersible rigs & platforms
- Cable and pipe penetrations in drilling, production and control modules
- Watertight and fire-rated sealing in hulls, decks and bulkheads
- EMP and EMC protection for communication, control and navigation systems
- Flood defence and environmental sealing in lower and submerged compartments

“The service provided by CSD was excellent in all aspects. The installation crew were skilled, hard-working and resourceful and also integrated well with our own men who supported then with the external duct sealing.”
